Crack sealed, new problems arise

[Ligerzero]

Well, kinda old, but i think this one has gotten abit worse.
ive sealed that crack on the BOV. But now, it feels as if the car is not getting enough fuel (this is on high boost mode). it judders around like when you are about to run out of gas. And now, there's a huge rattling noise just under the exhaust manifold, both on idle, and when driving (low boost mode tho doesn't bring it out when driving, just idling). Turbo on its way out? Any help would be appreciated.

Ill gladly take a small vid of it if needed to.

that would b a good idea dude.. as i cant quite figure out whats wrong.. unless ur bov is leaking, which would cause erratic idle & loss of boost .. but thats not when ur boosting, this would affect idle mainly..

"it feels as if the car is not getting enough fuel (this is on high boost mode). it judders around like when you are about to run out of gas."
like bad petrol...only on high boost? sounds like your leads or plugs mate..thats what was wrong with mine

dont know about the other noise

 

[Ligerzero]

yeh, kinda like bad petrol. and yes, this only happens on high boost. nothing whatsoever on low.

backfires also so..if so i would put my bet on plugs leads as i had the exact same prob..

 

[Ligerzero]

nope, it doesnt backfire at all. Well it feels like its going to, but it doesnt.

here's the not so good vid. Turn treble up, as you could hear it abit.

while im waiting for the vid to load..do you have a full system exhaust?

 

[Ligerzero]

no, car is plain stock standard cept air filter, that's all.
And pod filter has been there for over a month now.

 

[GT-TD04]

prob wouldn't backfire with the standard exhaust.still waiting on the vid(damn dial up)

 

[GT-TD04]

damn youtube just froze on me ...just change your plugs first(sometimes they look grand but their fooked) and if that doesnt help try your leads.sorry i cant be anymore help

I might as well get it in for service this week if that's the case.

same prob with my car now.. changed the plugs and there abit of a improvement but still juddering abit and it doing this on low mode too!! it idles about 600rpm!!

Hrmmmmm. just went and checked it again.
The rattling noise seems something is very very loose, as in high revs, it rattles like a bitch. At low revs, nada cept when engaging gear (which shakes the engine abit).
